LSISAllZ JOHN I). ROSS, OF ]?ASADENA, CALIFORNIA.

SPRINKLER NOZZLE.

Application led April 12, 1921.

To all whom t may Concern Be it known that I, Jol-1N D. Ross, a citizen of the United States, residing at Pasadena., in the county of Los Angeles, State of California, have invented neiv and useful liul'iiovcments in Sprinkler Nozzles, of which ,the following is a specification.

My invention relates to a sprinkler nozzle of the type. illustrated and described in my U. Letters Patent No. 752,803, of February 23, 1904, entitled Nozzle for sprinklers, and pertains to an improvement thereon.

In the construction illustrated and described in patent above referred to, the streams of ivatell issued from a centrally disposed group of perforations in the sprinkler plate or head in an uneven manner, due mainly to an uneven pressure Within the sprinkler chamber, the streams at the sprinkler ends issuing with greater force therefrom than from the centrally disposed group of pertorations.

By means of my improved device the streams of Water will issue from the various perforations in an even and uniform manner, the pressure being equally distributed in the chamber behind the perforated plate or head.

Yhe above object is accomplished by means of the device disclosed herein and illustrated in the accompanying drawings, in which:

Fig. l is a side elevation of my improved sprinkler' nozzle.

Fig. 2 is a central longitudinal section through the same.

Fig. 3% is a cross section et the nozzle taken on line 3 3 of Fig. l.

Referring more specifically to the drawings, 5 designates a sprinkler nozzle, preferably insisting of an elongated Water pressure chamber (i, provided with a bottom Wall T, side walls a perforated top wall 9 of .segmental foi-1n. cud walls `1 0 and a threaded water inlet hose coupling ll secured to the bottoni ivall and located midway of end walls it). The whole construction is prefer'- ably formed of a non-corrodible metal such as sheet brass and formed by means of dies.

The sprinklerl perforations are formed in the segmental Wall 9 at right angles thereto, so that the streams of Water issuing therefrom will be directed in a fan shape.7 All of the above construction is substantially the same as illustrated and described in my patent heretofore referred to.

Mounted directly above the Water inlet 11 Serial No. 460,731.

of chamber 6 and approximately midway betiveen bottom Wall 7 and top Wall 9 is a horizontally disposed `water deiiecting pla-te let, its side edges seating ivithin depressions l5 formed in the side Walls S of the sprinkler water pressure chamber.

By means of the above construction the stream of water passing into chamber (3 will be evenly distributed so that the streams Will issue from all the perforations in the Wall 9 in a uniform manner instead of the perforated segmental top wall 9, thereby equalizing the Water pressure evenly throughout the area of chamber 6, the streams issuing from all the perfor-ations in a uniform manner.

What I claim is:

l. In a sprinkler nozzle construction, a sprinkler head forming a Water pressure. Chamber, one Wall of said chamber being of elonpated segmental form with parallel side edges, said Wall being provided With a plurality of water discharge outlets or perforations, the oppositely disposed Wall being provided with a Water inlet opening, a threaded hose connection secured in said inlet, and a detiecting plate rigidly mounted above the Water inlet and disposed transversely thereof.

2. A sprinkler nozzle construction comprising a casing having a Water inlet leading thereto and a plurality of Water discharge outlets, said discharge outlets occupying an area of elongated curved formation, and a detlector plate arranged in the path of the Water from the inlet to the central discharge outlets.

A sprinkler nozzle construction, comprising a metallic casing consisting of side, end, bottom and top walls forming an elongated pressure chamber, the top ivall of said casing being prmf'idcd with a plurality ot perforations or water fjiutletfi' ivater inlet pipe being disposed substantially midway of the ends of said casing, and a detlecting plate rigidly mounted in said chamber directly above the water inlet lea-ding thereto, whereby the water will issue through all the perforations in the top ivall with equal force.

In witness that I claim the foregoing I have hereunto subscribed my name this 29th day of March, 1921.

JOHN D. ROSS.
